That just means you have 0xff in the alpha channel, right? (try printf in
hex, -1 is 0xffffffff in 2's compliment 32bit) We can decide what the
vanilla GGI primatives should do with alpha after we've got LibBuf/LibBlt
in line. Though if it's rgba white would be 4294967040 (unsigned,
-256 signed) if the alpha was zeroed.
